Fraud management systems (FMSs) are designed to detect, manage, and assist in the investigation of fraudulent events.

They rely on data provided by various elements to identify abnormalities in traffic patterns and report suspicious activity that might suggest fraudulent, irregular, or otherwise abusive activity is being engaged.

This tutorial discusses the crucial role played by FMSs in the containment of next-generation fraud, the vulnerability of Internet protocol (IP)–based technologies, effective data analysis and algorithms, and solution methodologies.

The open and distributed nature of convergent and next-generation network (NGN) architecture enables easy access to services, information, and resources, together with the constant abuse of hackers, curious individuals, fraudsters, and organized crime units. Fraud perpetrators introduce new, complex techniques of fraud daily, possessing the knowledge to circumvent all network security mechanisms. Their intrusion is nearly impossible to detect, causing immense damage to operators and service providers alike.

Consequently, a new approach to fraud management is being introduced to tackle these threats.
